Procedure

In a 10 mL round-bottomed flask, the above prepared N1-(3-((3S,8S,9S,10R,13R,14S,17R)-10,13-dimethyl-17-((R)-6-methylheptan-2-yl)-2,3,4,7,8,9,10,11,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthren-3-yloxy)propyl)-N4-((S)-1-(4-fluorophenyl)-4-((S)-1-(4-(hydroxymethyl)phenylamino)-6-((4-methoxyphenyl)diphenylmethylamino)-1-oxohexan-2-ylamino)-4-oxobutan-2-yl)succinamide (196 mg, 160 μmol, Eq: 1.00) and Huenig's base (61.9 mg, 81.4 μl, 479 μmol, Eq: 3.00) were combined with CH2Cl2 (1.6 ml) and DMF (0.8 ml) to give a yellow suspension; bis(4-nitrophenyl) carbonate (72.8 mg, 239 μmol, Eq: 1.50) was added and the reaction allowed to proceed at ambient temperature over night. The mixture was poured onto crashed ice/NH4Cl (pH ˜6), extracted 2× with AcOEt, washed with H2O and brine, dried over Na2SO4, and evaporated to dryness. After trituration with AcOEt/heptane one obtained 123 mg of the title compound as light yellow solid. MS: expected mass: 1392.7825, found mass: 1392.7819.
